Replacements?

I'm trying to cut down fr this time + dry right now. I'm chronically ill, so smoking has been the best there is available for chronic stomach isses and other body stuff. What can I use to replace the THC+CBD and still help? I've been smoking mostly chamomile today and it kinda works for the mental side. forewarning, i am not trying to quit and there is pretty much nothing [in terms of conventional treatment available to me] have tried that works in a similar way (pain relief, dopamine, anti-nausea).
